1Information about SunPower's use of non-GAAP financial information, including a reconciliation to U.S. GAAP, is provided under "Use of Non-GAAP Financial Measures" below.

"We executed well as we met or exceeded our key financial guidance metrics for the first quarter while laying the foundation for improved profitability in the second half of the year," said Tom Werner, SunPower CEO and chairman of the board.

"Demand in our global DG business remains strong and we expanded shipments into the international power plant market. In the first quarter, we introduced exciting new products in both the upstream and downstream parts of the value chain. Upstream, we introduced a new portfolio of residential Maxeon and P-Series panels for both U.S. and international residential markets and we are already seeing significant demand for these new products in our global DG business. We also began shipment of P-Series panels from our Oregon factory and the ramp of our 25 percent efficient Maxeon Gen 5 cell technology in Fab 3 is continuing. In our downstream business we unveiled a revolutionary online, instant design platform for our North American residential market that will improve customer experience while reducing costs.

SunPower Energy Services (SPES) - North American Residential and Commercial Businesses"In the first quarter, our residential business was impacted by unusually severe weather and related installation delays in several key markets which limited MW volume. However, we offset this impact due to our prudent management of expenses, improved operational efficiency and a stable pricing environment. Customer response to the launch of our new A-Series panel, the industry's first 415-watt residential module, has been very strong and we expect to allocate all of our capacity for this product to the U.S. market at least through the end of 2019. Additionally, we continued to see further traction for our loan product as deployed MW tripled year over year. With forecasted MW growth of 15 percent, our New Homes backlog of 35,000 customers and the launch of both our Equinox storage and services platform and our instant design digital application in the second half of the year, we are confident in our ability to meet our residential installation targets in 2019.

"In Commercial, we continued to build on our market leadership position, adding both new and existing customers to our 1.3 gigawatt (GW) installed base. Interest in our Helix solar-plus-storage solution remains high as our storage pipeline now exceeds 110-MW with attach rates in excess of 35 percent. We are also well positioned for significant growth in the second half of the year given our first quarter bookings, with more than 80 percent of our 2019 volume forecast now in backlog.

SunPower Technologies (SPT) - Manufacturing, International DG / Power Plant panel businesses"SunPower Technologies, which manufactures, designs and sells the world's most efficient solar cells and panels, also posted solid financial performance for the quarter, exceeding revenue and shipment forecasts. The ramp of our Maxeon Gen 5 solar cell and panel technology is continuing and we recently commenced tool installation for our second manufacturing line which will bring nameplate Maxeon Gen 5 capacity to approximately 250 MW by the end of the year. Additionally, the ramp of P-Series production in Oregon is also continuing with U.S. shipments planned for up to 150 MW this year. In our panel sales business, we are benefitting from our new, DG-focused international channel strategy as Europe, Japan and Australia all exceeded their revenue and shipment plans in the first quarter. Customer response in our core international DG markets to our new 400-watt Maxeon and new P-19 residential panels has been very strong, and we are currently fully allocated for both of these products in the second quarter with bookings now building for the second half of 2019. We are also executing on our robust pipeline of P-19 demand for the global power plant business, where we are fully booked for the balance of 2019. Finally, we are operating our fabs at 100 percent utilization to meet the strong demand for our products as well as the production of up to 200 MW of panels for our 2019 U.S. safe harbor program," Werner concluded.

"Solid execution enabled us to meet or exceed our key financial guidance targets for the quarter as we positioned ourselves for a strong second half of the year," said Manavendra Sial, SunPower chief financial officer. "We continued our focus on improving cash flow while further investing in our growth initiatives. We also expect to receive $87 million from closings under the previously announced sale of our commercial sale-leaseback portfolio in the second quarter, as well as finalizing certain strategic DG financing programs that we believe are more capital efficient while improving margins. We remain committed to achieving positive cash flow at the business unit level in the second half of the year while improving our profitability throughout 2019."

First quarter fiscal year 2019 non-GAAP results exclude net adjustments that, in the aggregate, improved non-GAAP earnings by $32.3 million, including $49.4 million related to cost of above-market polysilicon, $8.3 million related to impairment and sale of residential lease assets, $5.7 million related to stock-based compensation expense, $4.9 million related to legacy sale-leaseback transactions, $2.6 million related to business reorganization costs, $1.8 million related to intangibles, $1.5 million related to tax effect, $1.4 million transaction-related costs, and $0.1 million related to utility and power plant projects, partially offset by $33.0 million related to unrealized gain on equity investment, $6.1 million related to gain on business divestiture, $3.7 million related to construction revenue on solar services contracts, and $0.6 million related to restructuring expense.

Financial OutlookThe company continues to expect financial performance to improve on a quarterly basis throughout fiscal year 2019 with performance weighted towards the second half of the year.

The company's second quarter 2019 GAAP and non-GAAP guidance is as follows: on a GAAP basis, revenue of $370 million to $410 million, gross margin of 0 percent to 3 percent and net income of $0 million to $20 million. On a non-GAAP basis, the company expects revenue of $420 million to $460 million, gross margin of 7 percent to 10 percent, Adjusted EBITDA of $(5) million to $15 million and MW deployed in the range of 550 MW to 600 MW.

The company's fiscal year 2019 GAAP and non-GAAP guidance is as follows: on a GAAP basis, revenue of $1.8 billion to $1.9 billion and a net loss of $120 million to $100 million. On a non-GAAP basis, revenue of $1.9 billion to $2.0 billion and operational expenses of less than $270 million. Gigawatts deployed is expected to be in the range of 1.9 GW to 2.1 GW in addition to the company's safe harbor program and capital expenditures of approximately $65 million.

The company is also raising its fiscal year 2019 Adjusted EBITDA guidance to the range of $90 million to $110 million compared to previous guidance of $80 million to $110 million.

The company will also host a conference call for investors this afternoon to discuss its first quarter 2019 performance at 1:30 p.m. Pacific Time. The call will be webcast and can be accessed from SunPower's website at http://investors.sunpower.com/events.cfm.

Use of Non-GAAP Financial Measures

To supplement its consolidated financial results presented in accordance with United States Generally Accepted Accounting Principles ("GAAP"), the company uses non-GAAP measures that are adjusted for certain items from the most directly comparable GAAP measures. The specific non-GAAP measures listed below are: revenue; gross margin; net loss; net loss per diluted share; and adjusted earnings before interest, taxes, depreciation and amortization ("Adjusted EBITDA"). Management believes that each of these non-GAAP measures is useful to investors, enabling them to better assess changes in each of these key elements of the company's results of operations across different reporting periods on a consistent basis, independent of certain items as described below. Thus, each of these non-GAAP financial measures provides investors with another method to assess the company's operating results in a manner that is focused on its ongoing, core operating performance, absent the effects of these items. Management uses these non-GAAP measures internally to assess the business, its financial performance, current and historical results, as well as for strategic decision-making and forecasting future results. Many of the analysts covering the company also use these non-GAAP measures in their analyses. Given management's use of these non-GAAP measures, the company believes these measures are important to investors in understanding the company's operating results as seen through the eyes of management. These non-GAAP measures are not prepared in accordance with GAAP or intended to be a replacement for GAAP financial data; and therefore, should be reviewed together with the GAAP measures and are not intended to serve as a substitute for results under GAAP, and may be different from non-GAAP measures used by other companies.

Non-GAAP revenue includes adjustments relating to 8point3, legacy utility and power plant projects, legacy sale-leaseback transactions and construction services for residential customer contracts, each of which described below. In addition to the above adjustments, non-GAAP gross margin includes adjustments relating to impairment and sale of residential lease assets, cost of above-market polysilicon, stock-based compensation, amortization of intangible assets, and depreciation of idle equipment, each of which is described below. In addition to the above adjustments, non-GAAP net loss and non-GAAP net loss per diluted share are adjusted for adjustments relating to gain on business divestiture, transaction-related costs, business reorganization costs, non-cash interest expense, restructuring expense, the tax effect of these non-GAAP adjustments, and other items, each of which is described below. In addition to the above adjustments as non-GAAP net loss, Adjusted EBITDA includes adjustments relating to cash interest expense (net of interest income), provision for (benefit from) income taxes, and depreciation.

Non-GAAP Adjustments Based on International Financial Reporting Standards ("IFRS")

The company's non-GAAP results include adjustments under IFRS that are consistent with the adjustments made in connection with the company's internal reporting process as part of its status as a consolidated subsidiary of Total S.A., our controlling shareholder and a foreign public registrant that reports under IFRS. Differences between GAAP and IFRS reflected in the company's non-GAAP results are further described below. In these situations, management believes that IFRS enables investors to better evaluate the company's performance, and assists in aligning the perspectives of the management with those of Total S.A.

8point3: The company includes adjustments related to the sales of projects contributed to 8point3 Energy Partners based on the difference between the fair market value of the consideration received and the net carrying value of the projects contributed, of which, a portion was deferred in proportion to its retained equity interest in 8point3 Energy Partners, at the time. Prior to the adoption of ASC 606, these sales were recognized under either real estate, lease, or consolidation accounting guidance depending upon the nature of the individual asset contributed, with outcomes ranging from no, partial, or full profit recognition. The company adopted ASC 606 on January 1, 2018, using the full retrospective method, which required it to restate each prior period presented. The company recorded a material amount of deferred profit associated with projects sold to 8point3 Energy Partners in 2015, the majority of which had previously been deferred under real estate accounting. Accordingly, the carrying value in the 8point3 Group materially increased upon adoption which required us to evaluate the company's investment in 8point3 Energy Partners for other-than-temporary impairment ("OTTI"). In accordance with such evaluation, the company recognized an OTTI charge on the 8point3 investment balance in fiscal 2017. On June 19, 2018, the company sold its equity interest in the 8point3 Group.

Legacy utility and power plant projects: The company includes adjustments related to revenue recognition of certain utility and power plant projects based on the ratio of costs incurred to date to the total estimated costs at completion of the performance obligations and, when relevant, the allocation of revenue and margin to the company's project development efforts at the time of initial project sale. Prior to the adoption of ASC 606, such projects were accounted for under real estate accounting guidance, under which no separate allocation to the company's project development efforts occurs and the amount of revenue and margin that is recognized may be limited in circumstances where the company has certain forms of continuing involvement in the project. Under ASC 606, such projects are accounted for when the customer obtains control of the promised goods or services which generally results in earlier recognition of revenue and margin than previous GAAP. Over the life of each project, cumulative revenue and gross profit will eventually be equivalent under both ASC 606 and non-GAAP once these projects are completed.

Legacy sale-leaseback transactions: The company includes adjustments primarily related to revenue recognition on certain legacy sale-leaseback transactions based on the net proceeds received from the buyer-lessor. Under GAAP, these transactions were accounted for under the financing method in accordance with the applicable accounting guidance. Under such guidance, no revenue or profit is recognized at the inception of the transaction, and the net proceeds from the buyer-lessor are recorded as a financing liability. Imputed interest is recorded on the liability equal to the company's incremental borrowing rate adjusted solely to prevent negative amortization. Under IFRS, revenue and profit are recognized at the time of sale to the buyer-lessor if certain criteria are met.

Unrealized (gain) loss in equity investments: The company recognizes adjustments related to the fair value of equity investments with readily determinable fair value based on the changes in the stock price of these equity investments at every reporting period. Under GAAP, unrealized gains and losses due to changes in stock prices for these securities are recorded in earnings while under IFRS, an election can be made to recognize such gains and losses in other comprehensive income. Such an election was made by Total S.A. Management believes that excluding the unrealized gain or loss on the equity investments is consistent with the company's internal reporting process as part of its status as a consolidated subsidiary of Total S.A. and better reflects the company's ongoing results.

Other Non-GAAP Adjustments

Impairment and sale of residential lease assets: In the fourth quarter of fiscal 2017, the company made the decision to sell or refinance its interest in the residential lease portfolio and as a result of this triggering event, determined it was necessary to evaluate the potential for impairment in its ability to recover the carrying amount of the residential lease portfolio. In accordance with such evaluation, the company recognized a non-cash impairment charge on its solar power systems leased and to be leased and an allowance for losses related financing receivables. In connection with the impairment loss, the carrying values of the company's solar power systems leased and to be leased were reduced which resulted in lower depreciation charges. In the fourth quarter of fiscal 2018, the company sold membership units representing a 49% membership interest in its residential lease business and retained a 51% membership interest. The loss on divestment and the remaining unsold residential lease assets impairment with its corresponding depreciation savings are excluded from the company's non-GAAP results as they are non-cash in nature and not reflective of ongoing operating results.

Construction revenue on solar services contracts: Upon adoption of the new lease accounting guidance ("ASC 842") in the first quarter of fiscal 2019, revenue and cost of revenue on solar services contracts with residential customers are recognized ratably over the term of those contracts, once the projects are placed in service. For non-GAAP results, the company recognizes revenue and cost of revenue upfront based on the expected cash proceeds to align with the legacy lease accounting guidance. Management believes it is appropriate to recognize revenue and cost of revenue upfront based on total expected cash proceeds, as it better reflects our ongoing results as such method aligns revenue and costs incurred most accurately in the same period.

Cost of above-market polysilicon: The company has entered into multiple long-term, fixed-price supply agreements to purchase polysilicon for periods of up to 10 years. The prices in select legacy supply agreements, which incorporate a cash portion and a non-cash portion attributable to the amortization of prepayments made under the agreements, significantly exceed current market prices. Additionally, in order to reduce inventory and improve working capital, the company has periodically elected to sell polysilicon inventory in the marketplace at prices below the company's purchase price, thereby incurring a loss. Management believes that it is appropriate to exclude the impact of its above-market cost of polysilicon, including the effect of above-market polysilicon on product costs, losses incurred on sales of polysilicon to third parties, and inventory reserves and project asset impairments from the company's non-GAAP financial measures as they are not reflective of ongoing operating results and do not contribute to a meaningful evaluation of a company's past operating performance.

Stock-based compensation: Stock-based compensation relates primarily to the company's equity incentive awards. Stock-based compensation is a non-cash expense that is dependent on market forces that are difficult to predict. Management believes that this adjustment for stock-based compensation provides investors with a basis to measure the company's core performance, including compared with the performance of other companies, without the period-to-period variability created by stock-based compensation.

Amortization of intangible assets: The company incurs amortization of intangible assets as a result of acquisitions, which includes patents, purchased technology, project pipeline assets, and in-process research and development. Management believes that it is appropriate to exclude these amortization charges from the company's non-GAAP financial measures as they arise from prior acquisitions, are not reflective of ongoing operating results, and do not contribute to a meaningful evaluation of a company's past operating performance.

Depreciation of idle equipment: In the fourth quarter of 2017, the company changed the deployment plan for its next generation of solar cell technology, and revised its depreciation estimates to reflect the use of certain assets over its shortened useful life. Such asset depreciation is excluded from the company's non-GAAP financial measures as it is non-cash in nature and not reflective of ongoing operating results. Excluding this data provides investors with a basis to compare the company's performance against the performance of other companies without such charges.

Gain on business divestiture: In the first quarter of fiscal 2019, the company entered into a transaction pursuant to which it sold membership interest in certain of its subsidiaries that own leasehold interests in projects subject to sale-leaseback financing arrangements. In connection with this sale, the company recognized a gain relating to this business divestiture. Management believes that it is appropriate to exclude this gain from our non-GAAP results as it is not reflective of ongoing operating results.

Transaction-related costs: In connection with material transactions such as acquisition or divestiture of a business, the company incurred transaction costs including legal and accounting fees. Management believes that it is appropriate to exclude these costs from the company's non-GAAP financial measures as they would not have otherwise been incurred as part of its business operations and are therefore not reflective of ongoing operating results.

Business reorganization costs: In connection with the reorganization of our business into an upstream and downstream business unit structure, the company incurred and expect to continue incurring expenses in the upcoming quarters associated with reclassifying prior period segment information, reorganization of corporate functions and responsibilities to the business units, updating accounting policies and processes and implementing systems to fulfill the requirements of the master supply agreement between the segments. Management believes that it is appropriate to exclude these from the company's non-GAAP financial measures as they would not have otherwise been incurred as part of its business operations and are therefore not reflective of ongoing operating results.

Non-cash interest expense: The company incurs non-cash interest expense related to the amortization of items such as original issuance discounts on its debt. The company excludes non-cash interest expense because the expense does not reflect its financial results in the period incurred. Management believes that this adjustment for non-cash interest expense provides investors with a basis to evaluate the company's performance, including compared with the performance of other companies, without non-cash interest expense.

Restructuring expenses: The company incurs restructuring expenses related to reorganization plans aimed towards realigning resources consistent with the company's global strategy and improving its overall operating efficiency and cost structure. Restructuring charges are excluded from non-GAAP financial measures because they are not considered core operating activities and such costs have historically occurred infrequently. Although the company has engaged in restructuring activities in the past, each has been a discrete event based on a unique set of business objectives. As such, management believes that it is appropriate to exclude restructuring charges from the company's non-GAAP financial measures as they are not reflective of ongoing operating results or contribute to a meaningful evaluation of a company's past operating performance.

Tax effect: This amount is used to present each of the adjustments described above on an after-tax basis in connection with the presentation of non-GAAP net income (loss) and non-GAAP net income (loss) per diluted share. The company's non-GAAP tax amount is based on estimated cash tax expense and reserves. The company forecasts its annual cash tax liability and allocates the tax to each quarter in a manner generally consistent with its GAAP methodology. This approach is designed to enhance investors' ability to understand the impact of the company's tax expense on its current operations, provide improved modeling accuracy, and substantially reduce fluctuations caused by GAAP to non-GAAP adjustments, which may not reflect actual cash tax expense.

Adjusted EBITDA adjustments. When calculating Adjusted EBITDA, in addition to adjustments described above, the company excludes the impact of the following items during the period:

Cash interest expense, net of interest income

Provision for (benefit from) income taxes

Depreciation

For more information about these non-GAAP financial measures, please see the tables captioned "Reconciliations of GAAP Measures to Non-GAAP Measures" set forth at the end of this release, which should be read together with the preceding financial statements prepared in accordance with GAAP.
